It has certainly been a busy 24 hours for those attempting to keep up to date on the latest additions to the ever-growing cast of X-Men: First Class.  First Jason Flemyng, then Rose Byrne, and now Oliver Platt has officially signed on to play a role in the new mutant origin flick.

X-Men: First Class revolves primarily around the exploits of the young Professor Charles Xavier (James McAvoy) and Erik “Magneto” Lensherr (Michael Fassbender), prior to their falling out over conflicting ideologies.  Director Matthew Vaughn claims the film is not a reboot, nor a traditional prequel to the X-Men film trilogy that began in 2000.

Platt will play a non-mutant character known as The Man in Black.  Who exactly this mysterious figure is remains unknown for now, though he likely has nothing to do with Lost and is probably not an agent working for a secret government organization that patrols extra-terrestrial activity on Earth. 😉

Kevin Bacon was unveiled as the First Class villain last month, though Platt could easily end up playing one of his cohorts.  The latter actor is not exactly know for playing dastardly figures – Platt tends to provide comic relief (see below) more often than not – but the fact that he will be a regular human in a X-Men movie indicates that this might be an exception.

First Class begins production in London this upcoming September and will reach theaters around the world next summer.  Between the recent news that Vaughn is revising portions of the First Class script that deal with Inception-type dream sequences, and the flurry of casting announcements over the past six weeks, it is difficult to gauge whether or not  this project is indeed being rushed, as has been suggested by our own Rob Keyes.

Vaughn’s output as a filmmaker so far has been pretty solid and he seems like an excellent choice on paper to helm the young X-men flick.  First Class will also be the rare blockbuster comic book adaptation scheduled to arrive in the next two years that will NOT be in 3D – or so it seems, for now.

X-Men: First Class arrives in theaters in the U.S. on June 3rd, 2011.
